A couple of things I have been thinking about it the "stats screen" was implemented. It could be fairly basic to start off with having:

-Rank-Races Won (Total races won out of how many you have started)-Win Percentage (From that result there could be a simple percentage)-Win Streak (How many games you have won in a row)-Perfect Corners (The number of perfect corners you have done out the total amount of corners you have done)-Perfect Starts (The number of perfect starts you have made out of the total amount of starts you have made (maybe with a little note stating what is required to get a perfect start i.e quicker than 0.33 or whatever it may be))-Total Winnings (The total amount of cash you have won from races only, so basically excluding boxes)
